Of those who answered you, 386 voters favored the proposition. (a)[2] Explain why this situation should not be considered as the finite population case. (b)[2] Check if the sampling distribution of the sample proportion can be approximately Normal. (c)[3] Construct the 92% CI for the favor proportion π. Sketch the CI. State if π can be 0.52. (d)[3] Construct the 96% CI for the favor proportion π. Sketch the CI. State if π can be 0.55. Hint: Round off probabilities and values to 5 decimal places. Refer to some Excel value lookups: NORM.
